CW069 is an allosteric inhibitor of HSET. CW069 showed marked activity against HSET in vitro. The inhibitor induced multipolar mitoses only in cells containing supernumerary centrosomes. CW069 therefore constitutes a valuable tool for probing HSET function and, by reducing the growth of cells containing supernumerary centrosomes, paves the way for new cancer therapeutics.

How to use

In Vitro:

CW-069 is an allosteric inhibitor of HSET with an IC50 of 75 μM. CW-069 shows statistically significant selectivity over KSP. CW-069 potently suppresses N1E-115 cells, and less potently inhibits the NHDF cells, with IC50 of 86 ± 10 μM and 181 ± 7 μM, respectively. CW-069 (100 or 200 μM) causes increased multipolar spindles in N1E-115 cells with supernumerary centrosomes and shows no effect on altering bipolar spindle morphology in normal human dermal fibroblast cells. CW-069 (200 μM) cacuses multipolar anaphase and cell death induced in N1E-115 cells via transfection with HSET siRNA, and antagonizes inhibition of KSP by monastrol, but does not exert mitotic arrest in HeLa cells.
